If you’ve been told you’re producing little or no sperm in your ejaculate, we could recommend MERC as a way of collecting sperm for treatment. If it’s not successful you might then go ahead with surgical sperm retrieval.
For the MERC test we’ll need you to provide us with several semen samples in one day – usually around three samples with two hours left between each.
Once you’ve given us the samples we’ll process them, finding any sperm that could be used in fertility treatment. If we identify sperm in your samples we might then freeze them to use in future treatments.
